Someone, a mum, has just turned up at our house in Eltham cheerily announcing "Hi, I'm Alex's mum" clearly expecting to pick him up. We've never heard of Alex or seen this woman before! Her son had a 'play date' this afternoon and she has clearly got the wrong address to pick him up from, and no idea where he is!
A bit of a distressing situation on the face of it, but I'm sure that through the parent network of mobiles and texts, she will find him, or Alex's play hosts will drop him off. Just goes to show, always check your kids' contact information.
